Operator Controls Focus - Remote Control (Green) Diode Laser Figure 1 Pre-Installation Installation and User Guide Introduction GENERAL All Gammex FOCUS - REMOTE CONTROL (GREEN) Laser Alignment Systems provide an optical aid for rapid and accurate patient positioning and repositioning for therapy and simulator machines. TECHNICAL DESCRIPTION Various combinations of the GLD-500-RC crosshair FOCUS - REMOTE CONTROL (GREEN) and the GLD-300-RC sagittal (straight line) FOCUS - REMOTE CONTROL (GREEN) are used with different systems. The GLD-500-RC lasers, mounted on each side, beam crosshairs along the X-axis. The crosshair GLD-500-RC laser, mounted on the ceiling, beams a crosshair vertically along the Z-axis. The Sagittal GLD-300-RC laser beams a straight line in the Z-Y plane. Installation Requirements ELECTRICAL Each laser is provided with a universal power supply (transformer) with an input of 100 to 240 volts at 50 to 60 Hz. The universal power supply plugs into a wall outlet with 4 interchangeable “snap-in” plugs to fit most outlets. A 1.2 meter (4 foot) power cord supplies 12 volt dc power to the laser with a screw-on power plug TOOLS NEEDED In addition to some basic tools, such as screwdrivers, hammer and ladder; you will need an electric hammer drill, plumb bob, level, water level, masking tape and 15M (50 feet) of string. (The mounting hardware, a 1/4-20 tap and tap drill, and 4 hex (Allen) wrenches (.050”, 1/8”, 3/32”, & 5/64”) are included with the lasers.) CAUTION: The location of the lasers is determined in relation to the therapy machine’s crosshair and isocenter. Before installing lasers, ask the physicist to verify that the field light aligns with the machine’s isocenter. Figure 1. Pre-Installation Focus - Remote Control (Green) Diode Laser Figure 2 Use a water level to line up the laser exit reference point at the height of isocenter. Pre-Installation Installation and User Guide Pre-Installation Use a water level, see Fig. 2, to line up the laser exit reference point at the height of isocenter. Use a level to verify: PREPARING THE ROOM • Gantry is level each time it is rotated 1. Unpack each laser, add the cord and plug into a wall outlet. • Template is placed accurately on wall 3. Set gantry and collimator to 0° and level the collimator. • Crosshairs on wall are at 90° angles 2. Turn the linear accelerator lamp on. 4. Lower the table as low as possible. COLLIMATOR CROSSHAIR ACCURACY The collimator-projected crosshair is used as a reference when determining the laser locations. The light field should coincide with isocenter, the gantry should be level and, if collimator crosshair displacement exists, it should be compensated for. 1. Project a crosshair onto a piece of paper taped to the table and mark the center with a dot. 2. Rotate through 360° and mark the center again. 3. If there is a difference between the two dots, find the center of the distance between the two dots. Mark this point and use this point as the crosshair center reference point. Use this point to line up the laser. USING THE WATER LEVEL Use a water level, see Fig. 2, to determine the height of the laser exit reference point when installing lasers in a simulator room or in a room with angled walls. In standard treatment rooms, the water level should also be used to verify the laser location. 1. Raise the table to the front pointer (isocenter). 2. Remove caps on ends of water level and remove air bubbles. 3. Line up with the table edge and with the wall. Figure 2 4. The water line on the wall indicates the horizontal axis of the laser exit reference point. Pre-Installation Focus - Remote Control (Green) Diode Laser Figure 3 Rotate the gantry 90° and project a crosshair onto the wall. Figure 4 Use a string to verify the location of the side lasers. 10 Side Laser Installation Installation and User Guide Installing Lasers SIDE LASER INSTALLATION For all GLD-500 RC installations. For angled walls, refer to page 35. Use a level to verify: • Gantry is level each time it is rotated • Template is placed accurately on wall • Crosshairs on wall are at 90° angles 1. Rotate the gantry 90° to the 270° position and project a crosshair onto the wall. Figure 3 2. Use a pencil and straight rule to trace the crosshair onto the wall. 3. Line up the template from page 56, so that the projected crosshair lines up with the laser exit point on the template. Use a level to line up the template. 4. Mark the outer edge of the template and also mark the mounting holes. 5. Rotate the gantry 180° to the 90° position and repeat steps 2-4 on the opposite wall. 6. Return the gantry to 0°. 7. Tape a piece of paper to the table. 8. Project a crosshair onto the paper, keep the field as wide as possible. 9. Hold the ends of a plumb bob on each wall until string shadow is in line with projected crosshair. Figure 4 10. The point at which the string hits the wall is the center of the laser exit point. Mark the center on the wall. Use the template to verify the location of the mounting holes. 11. Drill the mounting holes. 12. Remove the FOCUS - REMOTE CONTROL (GREEN) from its carton. Remove two screws at the top of the cover using a 5/64” hex (Allen) wrench. Slide the cover up, to disengage it, and lift the cover out. Remove the packing support from the optics and remove the plastic tie from around the optics.

Turn on the laser. The push switch will toggle on and off. The switch should light and the laser lines project. 16. Plug in the remote control receiver. 17. Rotate the gantry 90° (so that the crosshair is projected onto the laser) and tape a piece of paper to the gantry head, covering the projected light field. 18. Adjust the laser so that the laser crosshair lines up with the collimator cross hair. Refer to the following pages for the methods for making laser adjustments. 19. Place a piece of paper directly in front of the laser. 20. Verify that the center of the projected collimator crosshair is centered on the top laser lens. 21. Adjust for straight lines if necessary. Refer to the following pages. 22. Turn off the laser. 23. Place the cover on the laser. Slide it downward to engage the pins, then replace the screws at the top of the cover. Take care not to jolt or bang the laser. 24. Check the alignment of the laser several times. Use the remote control for minor adjustments. 25. Return the gantry to 0°. Side Laser Installation 13 Focus - Remote Control (Green) Diode Laser Remote Control Remote control is a radio communication feature that allows the operator to align as many as five lasers with one hand-held controller. Each Focus laser has a separate wall mounted receiver that communicates with the operator's transmitter. The receivers and transmitter all have an ID switch. The ID switch sets the identification number for the system. This allows different rooms to operate remote control lasers in close proximity without interference. All remote control receivers in a room will have the same ID number. Different rooms will have different ID numbers. To communicate properly, the transmitter ID must be set to match the receiver IDs of all of the laser receivers in a system. SETTING THE TRANSMITTER ID The transmitter ID switch is accessible through the battery compartment. To set transmitter identification, remove the battery cover and locate the switch. It will have three small toggles labeled 1, 2, and 3. Each toggle has an "on" position and an "off" position. For ID one, set switch 1 "on" and all other switches "off". For ID two, set switch 2 "on" and all other switches "off". ID three has 1 and 2 "on" and 3 "off". ID four has 3 "on" and all other switches "off". This sequence can continue up to ID seven which has all switches "on". The following table gives all of the combinations. 14 Operator Controls Installation and User Guide ID Verify that the id switch settings on all receivers in a system match the transmitter ID switch setting. SWITCH 1 SWITCH 2 SWITCH 3 OFF OFF OFF ON OFF OFF OFF ON OFF ON ON OFF OFF OFF ON ON OFF ON OFF ON ON ON ON ON SETTING THE RECEIVER LASER NUMBER The other switch on the bottom of the receiver selects the number for the laser. This corresponds directly to the laser number selection on the hand held transmitter. Each receiver has a switch with five positions. These positions represent the number of the laser that the receiver controls. If we move the first lever down and the rest up, then that makes the receiver number one, and the laser connected to it is also number one. The second lever stands for number two, and the third lever stands for number three. Only one lever may be in the down position for any given receiver. The other four switch levers must be up. Operator Controls 15 FOCUS - Remote Control (Green) Diode Laser The remote control receivers can be mounted to a wall, ceiling or other appropriate surface using two #8 screws (not included), spaced 1.5” apart. Keyhole slots in the back of the receivers will then fit over the screw heads and hold the receivers in place. The receivers can be damaged by radiation and should therefore be mounted outside of the radiation field. Once mounted, connect each receiver to its corresponding laser with the included cable. The remote control transmitter can be damaged by radiation and should not be left in the radiation field. To Align the lasers using the Remote Control 1. Plug in the receiver if they are not already connected. 2. Push the unlock button to activate the transmitter. The transmitter light should turn on. 3. On the transmitter, select the number of the laser that you wish to align. 16 Laser Positioning Adjustments Installation and User Guide 4. The corresponding receiver light should come on. 5. Move the laser line to its correct position. This button moves the laser line upward or toward the head This button moves the laser beam downward or toward the feet Laser Positioning Adjustments 17 Focus - Remote Control (Green) Diode Laser This button moves the laser beam to the left This button moves the laser beam to the right. 6. When the line is correctly positioned, push the lock button to secure alignment. The transmitter light will go out. If the lock button is not pressed, the transmitter will automatically lock the lasers and go into hibernation after 90 seconds of inactivity. 18 Operator Controls Installation and User Guide 8. Repeat the procedure for each laser that needs alignment Operator Controls 19 Focus - Remote Control (Green) Diode Laser Movement of Crosshair and Sagittal Laser Figure 6 20 Laser Positioning Adjustments Installation and User Guide Coarse Carriage Adjustments The carriage on which the laser is seated can be moved both horizontally and vertically. Coarse vertical adjustment of the laser carriage. 1. Loosen the hex head cap screws (B) with a 1/8" hex wrench. 2. Now use the wrench to turn the setscrew (A), which moves the carriage vertically. 3. When vertical adjustment is satisfactory, tighten the hex head cap screws (B) firmly.

Fine Horizontal and Vertical adjustments of the crosshairs and lines can be made using the remote control as shown on the following pages. 22 Laser Positioning Adjustments Installation and User Guide Focus - Remote Control (Green) Laser Positioning Adjustments Figure 6 shows schematically the positioning adjustments available on the FOCUS REMOTE CONTROL (GREEN). Figure 7 shows the different adjustments available on the FOCUS - REMOTE CONTROL (GREEN). The FOCUS - REMOTE CONTROL (GREEN) has both coarse and fine horizontal position adjustments. The remote control fine adjustment has limited range and is factory set in the middle of the range. If the limit of the range is reached, run the remote control a short distance in the opposite direction. Then use the coarse adjustment to move close to the desired position. Finally use the remote control fine adjustment to accurately position the crosshair. Focus, angularity, and line curvature are factory set and should not require adjustments at installation. Adjustments are available, if required, and are explained on the following pages. Laser Positioning Adjustments 23 Focus - Remote Control (Green) Diode Laser Laser Coarse Rotational Positioning The FOCUS - REMOTE CONTROL (GREEN) optics can be rotated for coarse horizontal positioning. To make this adjustment, loosen the setscrew as shown using a .050 hex wrench. The entire optics assembly can be rotated by hand, left or right, to move the crosshair horizontally. This is a very coarse adjustment. The setscrew must then be re-tightened. A fine-tuning adjustment can then be used to accurately position the crosshair. 24 Laser Positioning Adjustments Installation and User Guide Curvature Adjustments The line curvature is factory set. Adjustment should not be necessary. If needed, the 2 adjustments on the right hand side of the optics are used to straighten either line of the crosshair. Use a 3/32" hex wrench. Figure 7 Figure 7 A.

Additional Installations 39 Focus - Remote Control (Green) Diode Laser Calibration and Adjustments – FOCUS - REMOTE CONTROL (GREEN) Warning - Risk of incorrect diagnosis of treatment. • Isocenter of alignment lasers must coincide with isocenter of diagnostic of treatment equipment. Test alignment of laser daily, before use, for first month of operation and weekly after first month. Newly installed equipment will shift as building walls and floor settle and as building materials dry out. Re-align lasers to isocenter before use, if they have moved. • The laser must be aligned with the diagnostic or therapy equipment to be safely useful. Only a GAMMEX service technician, Medical Physicist, Biotech Engineer or Service Technician should perform alignment. Caution - Laser Light Risk of eye damage. Do not stare into beam. • Alignment procedures need to be performed with laser on. • Look only at laser light reflected from a diffuse surface (like paper or a wall). See Simplified Room Layout for general concept of laser alignment. Removing the Cover FOCUS - REMOTE CONTROL (GREEN) routine adjustments can be made with the remote control. Some adjustments and repairs require the removal of the cover. Remove this cover, as follows: First, turn off the laser. Unplug the power cord from the main socket. Remove two screws at the top of the bottom cover using the 5/64” Allen wrench. Slide the cover up, to disengage it, and lift the cover out. Plug in the power cord and on laser for adjustments. To replace the cover after making adjustments, reverse the process. Turn off the laser. Unplug the power cord. Tilt the top of the cover slightly away from the wall. Slide the two bottom fasteners into slots in the bottom end plate. Tilt the top of the cover toward the wall so that two holes in the top corners align with holes in the top end plate. Secure the cover with two side screws at the top corners. Take care not to jar the laser. Plug in the power cord. 40 Laser Calibration and Adjustments Installation and User Guide Calibration and Adjustments – FOCUS - REMOTE CONTROL (GREEN) GENERAL Test the alignment of the lasers daily, before use, for the first month after installation. After the first month test the system at least weekly. Isocenter of the alignment lasers must coincide with the isocenter of the diagnostic or treatment equipment. CEILING AND SAGITTAL LASERS Tape a piece of typing paper to the table under the gantry (Leveled and Set at 0°). Project a crosshair on the paper from the gantry. Mark the center point. Move the gantry out of the way. Project the Ceiling laser crosshair on the paper. Raise and lower the table. The center of the crosshair should align with the dot on the paper. In the same way the Sagittal line should pass through the dot on the paper. SIDE LASERS Turn on both side lasers. Use a piece of typing paper held perpendicular to the laser light. The two-projected laser crosshairs should line up on the paper (Figure 13). With the gantry at 0° (Leveled and Set at 0°) use a front pointer (Figure 14) to verify that both side lasers hit isocenter. If there is not a front pointer, raise the table to isocenter and project a crosshair on the table to verify that the side lasers hit isocenter. ADJUSTMENTS In a new installation some building movements can be expected. In most cases the fine adjustments made by pushing the remote control buttons as shown on pages 16 to 19 should be sufficient to make any adjustments. The remote control adjustments have limited range. If the remote control adjustment is at the end of the range, run it a short distance in the opposite direction. Use a coarse adjustment to come close to the desired position and use the remote control adjustment to zero in. Pages 20 through 30 outline various adjustments available on the FOCUS - REMOTE CONTROL (GREEN). In most cases only the remote control horizontal and vertical adjustments will be needed. Laser Calibration and Adjustments 41 Focus - Remote Control (Green) Diode Laser Troubleshooting PROBLEM NO LASER LIGHT POSSIBLE CAUSE POSSIBLE REMEDY Wall switch not on. Check switch by turning laser off and on. Wall switch not in full on position. Verify switch lever is in the full on position. Plug/connector not plugged in. Verify plug is in the fully Plug partially plugged in. plugged in position. Power supply not functioning. INTERMITTENT LASER Use voltmeter to measure the voltage output of the power supply wall plug. If voltage less than 11 or greater than 13 VDC, the power supply will need to be replaced. Call Gammex Sales and Service for assistance. Use voltmeter and check power supply. See above. Repair Warning - Use only repair parts specified by Gammex. Some parts may be similar, but may result in unit drifting out of alignment, early failure or being out of compliance with laser regulations. See pages 43 through 48 for FOCUS - REMOTE CONTROL (GREEN) repair instructions. Maintenance & Cleaning Once installed, Gammex Lasers require no maintenance other than cleaning of mirrors, beam splitters, and lenses according to standard optical practices. Occasional outside dusting of the green plastic window in the cover may be necessary. The window is very delicate. Use only a camera lens brush or other soft brush for this purpose. Clean other outside surfaces of the laser, receiver and transmitter with a soft cloth slightly moistened with water or a mild detergent solution, then wipe the surface with a dry cloth. Do not use any type of abrasive pad, scouring powder or chemical solvent such as thinner, benzene, alcohol or disposable wipes as these may damage the finish. Should a laser fail to function properly, contact Gammex Sales and Service. 42 Troubleshooting Installation and User Guide Repair REPLACING THE LASER DIODE CAUTION Laser Light. Risk of eye damage. If the Laser Light fails it can be easily replaced with a new laser diode. TOOLS REQUIRED: 5/64" & 3/32" Hex Allen Wrenches. 1. Turn off the FOCUS - REMOTE CONTROL (GREEN) by pressing the ON/OFF switch. Disconnect the power plug from the bottom of the FOCUS - REMOTE CONTROL (GREEN). 2. Remove two screws at the top of the cover, using a 5/64" hex (Allen) wrench . Slide this cover up to disengage it and lift the cover out. Figure 17 3. Remove FOUR (4) 4-40 socket head caps screws (using a 3/32" hex (Allen) wrench) that hold the lead shield over the cylindrical laser diode. Figure 17. 4. Lift off the lead shield and remove the laser diode. 5. Remove the plug at the end of the laser diode electrical leads from the circuit board. This plug snaps in and out of the socket in the circuit board. Figure 18. 6. Remove the old laser diode. 7. Place the new laser diode in the groove that held the old laser diode. Space the diode 3/8" from the round black lens in front of laser diode. The spacing is not critical and has little effect on the focus. 8. Re-attach the lead shield to the top of the laser diode, using the four 4-40 screws. Retighten evenly, keeping the top of the lead shield level. Do not over tighten.

If necessary, make focus adjustment as outlined in the Installation and User’s Guide. Focus adjustments must be made with the cover off. 10. Replace the cover. 11. Check the positioning of the laser crosshair or line. If necessary, make position adjustments as outlined in the Installation and User’s Guide. Check the alignment of the laser with the cover on and off. REPLACING THE TRANSMITTER BATTERIES The transmitter has a battery compartment on the back that can be opened by pushing down on the catch and sliding it toward the end of the case. The cover may be tight. It may be necessary to very carefully pry the opening apart at the parting line 44 Repair and Parts Information Installation and User Guide REPLACING THE TRANSMITTER BATTERIES (continued) It is very important to replace the batteries with the proper polarity in the right direction as shown. The spring contact always matches the negative ( -) end. These batteries are not rechargeable. Do not try to recharge them. They are long life lithium batteries. Transmitter batteries will not often require replacement, but when they do, they are available from Gammex Sales Department.
